Digital markets and disruptive technologies have radically reshaped investor behavior. As this book explains, social media, algorithmic trading, and gamified platforms amplify fundamental behavioral biases such as overconfidence and loss aversion. These “digital investors,” driven by real-time information and herd dynamics, are pushing markets into increasingly unstable territory—beyond the reach of traditional frameworks. Measuring digitally-driven irrationality with outdated metrics is no longer viable. Regulators aim to keep markets open and transparent, yet investors and platforms struggle to navigate new rules designed to protect both markets and consumers. This book explores the critical intersection of human psychology, technology, and financial governance in a world of constant change.
